+### Clean Command
+
+The `clean` command removes approval files for test cases that no longer exist:
+
+```bash
+pnpm run clean
+```
+
+This is useful when you've deleted or renamed test cases and want to clean up the corresponding approval files. The command will:
+
+- Scan all approval files in the `approvals/` directory
+- Check if each approval corresponds to an existing test case
+- Remove approvals for test cases that no longer exist
+- Report how many files were cleaned
+
 ### Skip Approval Mode
 
 Use `--skip-approval` (or `-sa`) to run tests in CI/CD or when you want to avoid interactive prompts:
